Lamborghini chief Stephan Winkelmann introduced the Aventador LP 750-4 Superveloce Roadster at Pebble Beach on Tuesday. Lamborghini gave the Aventador LP 750-4 Superveloce an even sexier sibling over the weekend, revealing the Aventador LP 750-4 Superveloce Roadster at Pebble Beach Concours d'Elegance. The half-million-dollar roadster packages the blistering performance of the Superveloce with a little more blue sky overhead, hitting the road as one of the hottest convertibles we've ever seen. The latest addition to Lamborghini's ultra-high-performance Superveloce family, the Aventador LP 750-4 Superveloce Roadster keeps pace with the Superveloce coupe in gaining 50 horsepower over its standard Aventador base. The naturally aspirated 6.5-liter V12 engine spits out 740 bhp (552 kW), plus 509 lb-ft (690 Nm) of torque. The rear window opens up to fill the cabin with that V12's glorious throaty growl. The Superveloce Roadster's V12 works in cooperation with Lamborghini's
seven-speed ISR transmission and Haldex Generation IV 4WD system, distributing power and torque to all four wheels. As in the Superveloce coupe, an adaptive Magneto Rheological Suspension, pushrod damping system and Lamborghini Dynamic Steering set-up help the driver transform that heady output into asphalt artwork. The vehicle loses 110 lb (50 kg) compared to the Aventador LP 700-4 Roadster, but it's still bit heavier than the Superveloce coupe. That means it lags ever so slightly behind in its 2.1 kg/hp (4.6 lb/hp) weight-power ratio and 2.9-second 0-62 mph (100 km/h) acceleration time (compared to 2.03 kg/hp and 2.8 seconds for the coupe). We don't think those minuscule drops will make anyone think less of the new super-convertible, though. Like the coupe, the Superveloce Roadster tops out just north of 217 mph (350 km/h). When the weather is less than ideal, the Superveloce Roadster protects driver and passenger with a two-piece carbon fiber hard top. As soon as the sunlight breaks the clouds up,
each 13.2-lb (6-kg) panel can stow away in the luggage compartment, providing one of the quickest, most furious wind-through-hair driving experiences on earth. Lamborghini plans to build 500 Superveloce Roadster models and offer each at a price of US$530,075. Deliveries will begin in early 2016.
